Star delta starter is a common used in domestic and industry sector to drive variant application such as chiller water pump,machinery,air-compressor and many more equipment.

Why star delta become common starter of motor control?

It is because this starter have a simple circuit diagram,low cost application and can drive for high horse power motor with low friction and can reduce starting torque with acceptable condition.

But this starter also tricky for beginner electrician and who not familiar with 6 wire electric motor.Actually it not too difficult if we have fully understanding the principle of star delta motor,starter sequence,circuit diagram and their operation.

For more detail please read my last post about star delta starter,star delta motor connection and many more topics about star delta in motor control categories.

If have any question or suggestion,please drop down your comment and we can share others circuit diagram design.one of my circuit diagram not too clear but i attached together with another circuit diagram for reference.

Example for star delta circuit diagram

* NOTE : This is one of circuit diagram design for star delta.It have variant design of star delta diagram depend on designer style for motor control.The important thing is it can operated with correct sequence and operation to avoid motor from serious damage or burn out.

Although electricity is used in every aspect of our lives, it is very dangerous for you to mess with if you haven’t been formally trained and educated. Whenever you have electrical problems, hire an electrician right away are the best in this field.

plz send me some pdf books of Electrician and circuit diagrams of Star Delta by my email address because I havn’t Internet facility in this company so just I will download it from email in Net cafe. “khaksaar22@yahoo.com” thanks for your attention
